Theranos
Theranos was an American privately held corporation that was touted as a breakthrough health technology company. Founded in 2003 by 19-year-old Elizabeth Holmes, Theranos raised more than US$700 million from venture capitalists and private investors, resulting in a $10 billion valuation at its peak in 2013 and 2014. The company claimed that it had devised blood tests that required very small amounts of blood and that could be performed rapidly and accurately, all using compact automated devices which the company had developed. These claims were later proven to be false. A turning point came in 2015, when medical research professor John Ioannidis, and later Eleftherios Diamandis, along with investigative journalist John Carreyrou of The Wall Street Journal, questioned the validity of Theranos's technology.
